(U) RE: [PHP] Protecting The images I work so hard to make

CLASSIFICATION: UNCLASSIFIED I've seen where some people will keep the images outside of the webroot. Then use file functions and the appropriate headers to display the image on the page.

Don't know if that helps or not... :) ---John Holmes... -----Original Message----- From: Philip Olson [mailto:philip@theprojects.org] Sent: Thursday, December 28, 2000 7:02 AM To: Toby Butzon Cc: Brandon Orther; PHP User Group Subject: Re: [PHP] Protecting The images I work so hard to make Toby, this is pretty interesting stuff, thanks!
